IMPROVEMENT IN RING RAILS AND HOLDERS FOR SPINNING.

Speoilication forming part of Letters Patent No. 135,944, dated February18, 1.873.

. shows ring G, adjustable ring-holder D, and

cross-sectionof ring-rail A through w y. Fig. 3

is a plan of theadjustable ring-holder D. Figs.

4 and 5 show sections of different kinds ofringsj"V and how applied toring-holder. Fig. 6 shows twister-rin g and traveler combined withadjustable ring-holder.

The rail A,shown in Fig. 1, is of`- iron, cast 'with the holes B. It hasthe grooves C planed so as to receive the adjustable ring-holder l).This holder is made narrower than the space between the grooves, whichrenders it adjustable by the screws E, and it is also shorter than thedistance between the centers of the rings, which renders it adjustablelengthwise of the rail. We, therefore,.can adjust the ring in anydirection that may be desired.

An importantfeature of this adjustable ring- Y holder is the slot F.When the sides ofthe holder are not pressed by the screws the slot isopen and will allow the puttin gin or taking out of the ring readily.When the ring is in the holder the screws are set up sufficiently tohold the ring fast, and the holder may then be adjusted as required.

By simply loosening one of the screws nearest the slot the ring can b eremoved or replaced 5 but the holder can be used with or without theslot F and can be adapted to any kind of ring that is desired to beused, as shown in Figs. 4

and 5. This arrangement is'particularly well adapted to the twister-ring and traveler, as shown in Fig. 6.

The old method of making the rails without the holder requires greataccuracy in drilling the holes for the rings, and bringing themconcentricwiththespindlesrequires expensive and nicely-constructed toolsfor doing the work and skilled and high-priced workmen to construct thispart ofthe machine; but by this construction the nicety of workmanshipand expense is not required. t

, It is alsowell known among manufacturers and operators of ring-Spinning machines that the ring-rail causes more trouble than all the restofthe machine, in consequence of the spindles gettin g out ofthe centerof the rings, there- Claims.
